Background: Hürthle cell carcinoma (HCC) of the thyroid is rare. There are contrasting data on its clinical behavior. The aim of this study was to describe clinic-pathological features and outcomes of HCC patients at our institution, in order to adapt our surgical management. Methods: We retrospectively studied 51 cases of HCC treated at the interdisciplinary endocrine center of the University Hospital of Cologne, Germany between 2005 and 2020. Results: Patients median age was 63 years (range 29-78) with 64.7% of cases being female. Primary treatment included surgery and postoperative radioiodine therapy with 3.7 GBq in all patients. Surgery consisted of total thyroidectomy in all cases and additional central lymphadenectomy in 90.2% of cases. The median number of harvested lymph nodes was 11 (range 2-31). Lymph node involvement was found in two (4.3%) pT4a tumors. In all other cases (95.7%), central lymphadenectomy was prophylactic and lymph nodes were free of metastasis in final histopathology. Twelve (23.5%) patients with incomplete biochemical response to primary treatment were diagnosed with structural relapse during the course of disease, for which seven (58.4%) underwent resection of isolated cervical metastasis. Histopathology revealed soft tissue implants in all cases and cervical surgery led to biochemical and radiologic cure in only two (28.5%) cases. Five (41.6%) patients developed metastatic disease, followed by systemic therapy in two patients. Vascular invasion of the primary tumor was significantly associated with relapse (p<0.01). Conclusions: Recurrence of HCC was common in this study. Given the low rate of lymph node metastases both in this study and in recent literature and the nature of relapse (soft tissue instead of nodal metastasis), the benefit of routine prophylactic central lymph node dissection for HCC remains unclear, especially in the absence of vascular invasion from the primary tumor.

This study focused on the difference between perceived and desired physician empathy (pPE and dPE) in the eye of patients with inflammatory bowel disease (IBD). It was investigated if a discrepancy (ΔPE) correlates with trust and satisfaction of patients. At the same time the aim was to gain detailed information about the subjective burden of disease and the resources of IBD patients, in order to better understand them. A modified version of the German Version of the Consultation and Relational Empathy (CARE) measure was completed as a paper-and-pencil questionnaire by IBD patients attending our facility (n = 32) and as an online survey by IBD patients at other locations throughout Germany (n = 89). Patients were in average 36.3±12 years old. The mean (SD) rating of pPE was 3.93 (0.96) on a scale of 1 to 5 (“poor” to “excellent”); however, the mean (SD) dPE was 4.38 (0.48) on the same scale. ΔPE correlated with perceived empathy and with patients’ satisfaction with treatment and trust in their health care providers. Patients reported quite a high subjective burden (mean [SD]: 2.93 [.63]) and named family, friends, and support groups as resources. Rather than assessing patient satisfaction with treatment and trust in their physician only with perceived PE, we suggest ΔPE as a useful additional parameter.

In rare diseases such as adrenocortical carcinoma (ACC), in silico analysis can help select promising therapy options. We screened all drugs approved by the FDA and those in current clinical studies to identify drugs that target genomic alterations, also known to be present in patients with ACC. We identified FDA-approved drugs in the My Cancer Genome and National Cancer Institute databases and identified genetic alterations that could predict drug response. In total, 155 FDA-approved drugs and 905 drugs in clinical trials were identified and linked to 375 genes of 89 TCGA patients. The most frequent potentially targetable genetic alterations included TP53 (20%), BRD9 (13%), TERT (13%), CTNNB1 (13%), CDK4 (7%), FLT4 (7%), and MDM2 (7%). We identified TP53-modulating drugs to be possibly effective in 20–26% of patients, followed by the Wnt signaling pathway inhibitors (15%), Telomelysin and INO5401 (13%), FHD-609 (13%), etc. According to our data, 67% of ACC patients exhibited genomic alterations that might be targeted by FDA-approved drugs or drugs being tested in current clinical trials. Although there are not many current therapy options directly targeting reported ACC alterations, this study identifies emerging options that could be tested in clinical trials.
